INSUFFLATOR Filed Feb. 16, 1957 Patented a... 2, 1940 UNITED STATES PATENT OFFIC 3 Claims.

This invention relates to vaginal insufllators, and the object of the invention is to provide a highly efficient and extremely simplified device for inflating the vagina to an extent whereby folds in the walls thereof will be straightened out; and whereby a medicament in the form of a finely divided powder will be injected into the extended vaginal cavity in the form of a cloud and which will, by proper manipulation of the device, be caused to settle on all parts of the smoothened walls and on the external surfaces of the patients anatomy immediately surrounding the vaginal orifice.

Another object of the invention is to provide the device with an insufilating nozzle and seal which may be readilydetached for sterilizing after each treatment.

Another object of the invention is to provide an insuffiating nozzle devoid of small openings which in devices in common use at the present time too frequently become clogged by secretions while inserting the device preliminaryt'o treatment and by which the powder is prevented from being evenly dusted onto and uniformly distributed over the walls of the vagina.

Another object of the invention is to provide a device which can be readily applied to containers in which the powder is originally packed for distribution, thus eliminating loss and inconvenience attending the filling of a receptacle forming part of the device from an original package.

Other objects and features of the invention will become apparent from the following description of the construction and operation of the device when taken with the accompanying drawing, of which: I

Fig. 1 is a longitudinal vertical section of the device attached to an original package of medicament; 3

Fig. 2 is a plan view; and I Fig. 3 is a transverse section taken on the line 3-3, Fig. 2.

As shown in Fig. 1, an original package of medicament in finely divided powdered form is shown as a glass or other jar, bottle or vial l, and which has a wide mouth or neck 2 in the present instance provided with external screw threads 3.

The device proper includes a cap 5-for the bottle l and which may be made of a suitable noncorrosive material, metal, hard rubber, Bakelite, etc. The cap 5 is internally threaded, as indicated at 4, for engagement with the threads 3 on the bottle I. The cap 5 carries a resilient washer 6 which is adapted to be drawn down tightly against the open end ofthe bottle I to make an air-tight seal between the bottle I and cap 5.

The cap 5 is provided with a head I from which extends in opposite directions, in the present instance, a pair of axially aligned projections 8 and 9. e

The projection 8 is shaped in a well known manner to fit within one end of a tube ill. The opposite end of the tube ill is attached to a hand bulb H, in the present instance, although it will be understood that the second end of the tube 10 maybe connected to any desired or available source of air under pressure or means for producing an air or other gaseous pressure in the tube lll.

The tube-receiving projection 8 is axially bored at [2 from its outer end inwardly to substantially the axis of the cap 5 where said bore l2 intersects a bore 13 which extends parallel to and closely adjacent the axis of the cap 5.

Secured in the bore l3 and projecting from the cap '5 into the bottle 4 to a plane substantially midway between the closed bottom and open top end of the bottle I is a tube I l which may be of non-corrosive metal, hard rubber, Bakelite, etc. and which is open at its lower or projecting end 15.

The second projection 9 on the cap 5 is threaded at Hi to receive a readily detachable nozzle l1 whereby said nozzle may be conveniently de tached for sterilizing.

The projection 9 and nozzle H are axially bored at [8 and 19 respectively to a uniform diameter throughout their respective. lengths and in alignment one with the other.

The bore IS in the projection 9comrnunicates and in the present instance intersects with a bore 28 formed in the head 1 of the cap 5 and which is disposed parallel to and immediately adjacent the axis of they cap 5. The bore is of equal diameter to the bore l'l-l8 and is preferably disposed with its axis in a common plane with the axis of the tube M, one at one side of the axis of the cap 5 and the other at the opposite side of said axis and both located as. close to the axis of the cap and to each other as possible or practical from a manufacturing point of view. r

The nozzle I9 is provided with a circular enlargement or collar 2|, which may be formed integral with the nozzle l9 or rigidly or adjustably secured therein as indicated at 23, if desired.

The collar 2| is preferably tapered toward one end and provided with a circular flange 22 adjacent its opposite end. A bell-shaped resilient cup 25 is firmly seated at its smaller end 26 on the tapered body of the collar 2! and is snugly seated against the flange 22, the outwardly flaring end 23 projecting backwardly over the nozzle is toward the bottle l or cap: 5.

The bell-shaped cup 25 is of such proportions or made in a variety of sizes that its external surface will fit snugly within the external orifice of the vaginal cavity to seal the same against ingress and egress of air, etc. to and from the interior of the vagina during-the insufliating operations.

The single bore [9 of the nozzle I! is of such a diameter that it will not become clogged by secretions during the inserting thereof or subsequently and which will conduct the finely divided powder while in suspension in air or other gaseous vehicle to the extreme end 31! of the nozzle at which the powder will emerge from the nozzle inv the form of a cloud.

The powder. propelled by the gaseous vehicle will be carried into contact with the Walls of the vagina which have been ballooned or smoothened or straightened out by pressure built up within the vagina, sealed by the guard 25 by the pressure of the gaseous vehicle supplied through the nozzle H.

The aseous vehicle is supplied through the bore if. of the cap 5 and enters the bottle I through the tube It. The lower end of the tube, by being located down Well in. the bottle i causes the gaseous vehicle passing th'erethrou'gh to im pinge upon the powder in the bottle I. This causes the gaseous vehicle to whirl in the bottle around the tube Hi and thereby agitate and carry along the finely divided particles of powder. The swirl of the air and powder suspended therein around the tube M passes upwardly in the bottle I and enters the bore 2B in the cap 5, from which the eddy currents of gaseous medium enters the bore l8 of the projection 9 and passes into the bore I2 of the nozzle H, from which it emerges in the form of a cloud as above noted.

After this procedure has been followed for a desirable length of time, the nozzle is withdrawn sl ghtly, breaking the seal produced by the guard 25. The pressure in the ballooned vagina. thereby is permitted to escape around the rim of the guard 25 and in so doing the cloud of medicated powder is caused to settle on the surfaces, etc. immediately surrounding the external orifice of the vagina.

After the treatment is completed, the nozzle I! may be readily removed from the cap 5 by unscrewing at it and the guard 25 may be readily slipped elf the nozzle ll so that they may be separately sterilized when desired.

While the device above described is made primarily for the treatment of humans, it may be produced in various sizes for the treatment of animals from the smallest to the largest.

I claim:

, 1. An insuiiiator comprising a container for finely divided powder; a cap on said container having an inlet passage therein, including a straight portion extending radially from a point near the center of the cap to the exterior surface of the cap and a straight portion extending axially of said cap and having its inner end communicating with the straight portion of said inlet passage and its outer end communicating with the interior of said container, the outer end of the straight portion of said inlet passage adapted for connection to a source of gaseous fiuid under pressure, said cap having an outlet passage therein including a straight portion extending radially from a point near the center of the cap to the exterior surface of the cap and a straight portion extending axially of said cap and having its inner end communicating with the straight portion of said outlet passage and its outer end communicating with the interior of said container; and a tube connected to the outer end of the axially positioned portion of the inlet passage in the cap and extending into said container a substantial distance below said cap, whereby the gaseous fluid under pressure flows through said tube and into the container to force the powder there-in through the outlet passage in said cap.
